I develop a Facebook application where i implemented the login with Facebook accounts using "https://graph.facebook.com/me?fields=id,first_name,last_name,email,picture&access_token=xxxxxx" end point from the Facebook API. With the data receive to the Facebook I created an user in my database where I can login with this.
Now, I must will get all the users Facebook which use the my Facebook application. There are a Facebook end point where i can receive from the API all the users Facebook in the JSON format ?
Thank you !!

No, there is not. You only get user ids when they log in – to store them appropriately for whatever purpose you need them for, is your responsibility.

Do you know if there is any way to publish on my web app the facebook messages published by the users on my facebook wall application?
I'm using spring social and I tried to use the code you can see below:
facebook.feedOperations().getPosts()
With this sentence, it is launched an exception alerting that Authentication is needed.
Thanks.

Nope. If you could, then Facebook would need to seriously evaluate their security. The user needs to give you permission to access their data. After authenticating can use the returned user token to access the user's Facebook wall posts.
I want to use "LOGIN with Facebook" function for the new website. I have created a page with a Facebook login.
When I am trying to get code from:
https://developers.facebook.com/docs/reference/plugins/login/
It is asking me to create an Application.
So my question is Can I use "Login with facebook" functionality without Facebook Application integration?
No, you can't. Even when you retrieve the code you need for the Login plugin, Facebook instructs you to substitute APP_ID for your own. You'll need an application if you want to retrieve data about that person when they login, for example
email
name
gender
location
etc...
You'll have to authenticate your users with an app_id and app_secret to retrieve an access_token. That access_token is unique per user per application. More info on authentication is here.
Basically, every time you want to query Facebook's databases, with the Graph API or FQL, you do so on behalf of the user. Facebook links these calls to applications so that they will be able to know which application has what permissions and also what they are doing with them.

I am using the Graph API for Facebook on my iPhone application. The problem is, I don't want the user to have to re enter their email address each time they want to login to integrate Facebook with my app. Is there a way to save and auto fill the login information using the Graph API?
Using the Graph API, there is no need for you to store the credentials, more than that, you should NOT store the credentials. As explained in the API dedicated help page the authentication process is handled by a secure token.
Meaning that if the user is already authenticated on Facebook using another application, it might be ( based on authentication process used ) already authenticated within your app.
You might check the token validity by using the isSessionValid method from the Facebook class.
Have a look to the iOS Facebook SSO link, it explains everything you need.
Is it possible to get the ID (Facebook Graph API) of a user who is currently logged in, without any access tokens?
If not, then how do I get new access tokens every time a user visits my page?
You will need to init the Facebook Javascript SDK and the user will have to have authorized your app at least one time. After that when the user visits your page as long as they are logged into Facebook you'll have access to the id and can retrieve it using
FB.getLoginStatus
the response will contain the information you're looking for.
Check this blog post for more details on setting up the FB init and the initial login.

You can check the facebook ID using their username

You can use the javascript sdk to get their accesstoken and let them allow your app.

I am trying to understand, how facebook authentication works and how the flow should look like. I am working with Google App Engine and I have managed to obtain first the code and then access token. Using it I can for example retrieve user's friends list. This is all cool.
However, how can I store this access_token? I wan to allow my user to access different pages in my facebook app and I will need this access token on those pages. How can I store it and how can I retrieve it? Or maybe no matter which page user accesses I first need to get the code and then access token and only then can I perform some operations on his behalf?
I don't want to use javascript sdk for now. Is it possible to do it all from server side?

just store the access_token in the datastore.

It is from the facebook python sdk.

If you don't want to use javascript sdk, you need to see this document. It has all details for facebook Oauth.

While facebook redirect your user to your page assigned by redirect_uri. It will give your the code (A_CODE_GENERATED_BY_SERVER), then your server can get the user's access_token/facebook id with server side facebook api + code. Then you can login your user (set the session/cookie) and do whatever you want.
